Answer:
Magnetic Field due to a Current through a
Circular Loop
Explanation:
We have so far observed the pattern of the magnetic field lines
produced around a current-carrying straight wire. Suppose
this straight wire is bent in the form of a circular loop and a
current is passed through it. How would the magnetic field
lines look like? We know that the magnetic field produced
by a current-carrying straight wire depends inversely on the
distance from it. Similarly at every point of a current-carrying
circular loop, the concentric circles representing the magnetic
field around it would become larger and larger as we move
away from the wire (Fig. 13.8). By the time we reach at the
centre of the circular loop, the arcs of these big circles would
appear as straight lines. Every point on the wire carrying
current would give rise to the magnetic field appearing as
straight lines at the center of the loop. By applying the right
hand rule, it is easy to check that every section of the wire
contributes to the magnetic field lines in the same direction
within the loop.We know that the magnetic field produced by a current-carrying
wire at a given point depends directly on the current passing through it.
Therefore, if there is a circular coil having n turns, the field produced is
n times as large as that produced by a single turn. This is because the
current in each circular turn has the same direction, and the field due to
each turn then just adds up.
